A Biopolymer Composite Material as an Anhydrous Proton‐Conducting Membrane

What a waste! A highly effective proton-conducting biopolymer has been prepared from imidazole and chitin phosphate, which is an environmentally benign, low-cost, and commonly discarded biopolymer (see picture). The composite material has a conductivity of 7×10−3 S cm−1 at 150 °C under anhydrous (water-free) conditions.
